Notes
- The discontinued Blue Arrow BA-TS-9.0 is a premier offering in the thin-wing servo class, engineered to deliver a top-tier blend of rapid transit speed and substantial holding power. It is tailored for the most demanding pilots flying high-performance aircraft like hotliners, pylon racers, and aggressive aerobatic models. In these disciplines, the ability to command an instantaneous change in direction is critical. The BA-TS-9.0's responsiveness ensures that control surfaces snap to attention the moment a command is given, providing the razor-sharp handling required for competitive flying. Its powerful motor ensures that even at blistering speeds, the control surfaces do not yield to aerodynamic pressure, a phenomenon known as blowback, which can lead to a loss of control authority.
- What truly distinguishes this servo is its ability to maintain its high performance under extreme stress. It is celebrated within the modeling community for its resilience and its "locked-in" feel. Pilots report a direct, one-to-one connection with their control surfaces, free from the vagueness or lag that can plague lesser servos. This gives them the confidence to fly on the edge, executing tight, high-speed maneuvers with the knowledge that the aircraft will respond precisely as commanded.
- From a robotics perspective, this combination of speed, power, and in-motion rigidity is highly valuable. The BA-TS-9.0 would be an exceptional choice for applications that require a fast actuator that must also hold a precise position against a dynamic or fluctuating load. For instance, it would be ideal for a robotic arm that needs to move quickly and then hold a tool steady during a delicate operation, or for the steering system of a high-speed autonomous rover that needs to make rapid, precise adjustments while traversing uneven terrain. Its slim profile remains a key asset, enabling powerful mechanisms to be built into space-constrained designs.
